TS Calculator (True Shooting Percentage)
Combine points, field-goal attempts and free-throw attempts into basketball true shooting percentage.
How the result changes
Only points scored changes; all other inputs stay at your current values. The line illustrates the formula across the shown range. This is not a forecast of real-world outcomes.
About this calculation
TS Calculator (True Shooting Percentage): Combine points, field-goal attempts and free-throw attempts into basketball true shooting percentage. Enter points scored, field-goal attempts, free-throw attempts; the reported quantities are true shooting percentage (%). The equations and examples below show how those inputs lead to the result and where the model's assumptions matter.
Formula
TS% = points / [2 × (FGA + 0.44 × FTA)] × 100
Worked example
With Points scored: 25 points, Field-goal attempts: 18 attempts, Free-throw attempts: 6 attempts, true shooting percentage is 60.56 %.
Method and inputs
The standard NBA-style estimate divides points by twice the sum of field-goal attempts and 0.44 times free-throw attempts. The 0.44 factor approximates possession use of foul shots. Multiply the ratio by one hundred for percent.
Worked example
With 25 points, 18 field-goal attempts and 6 free-throw attempts, the denominator is 2 × (18 + 2.64) = 41.28. True shooting percentage is about 60.56 percent.
A player with 25 points on 18 field-goal attempts but no free throws would have a different denominator from the example with six free-throw attempts. Free throws create scoring chances while consuming some possession value, which the 0.44 factor approximates.
How to read the result
True shooting combines scoring from two-point goals, three-point goals and free throws. It is not the literal fraction of shots made, and exceptional single-game results can be above one hundred percent in unusual cases.
True shooting and eFG answer distinct questions. eFG ignores free throws but adjusts made threes; true shooting includes free-throw attempts and total points. A high-foul-drawing player can rank differently under the two measures without either formula being wrong.
Assumptions and checks
The approximation treats free-throw attempts using a fixed 0.44 factor, which does not precisely represent every foul sequence. The game records must be from the same player or team and same sample period. At least one attempt must be present.
Do not substitute made free throws for attempts. Also avoid entering points per game with season-total attempts; the units must use the same aggregation. A comparison between players should consider role, shot difficulty and sample size.
Common questions
What does the ts calculator (true shooting percentage) calculate?
It estimates scoring efficiency per shooting possession with the familiar true-shooting formula, expressed as a percentage.
When should I recalculate or check another method?
Recalculate when corrected box-score figures arrive. Compare the resulting percentage with a relevant league, season or role context rather than applying a universal good-versus-bad cutoff.
